Now You Can Use Amazon ElastiCache for Redis with In-Transit and At-Rest Encryption to Help Protect Sensitive Information

Amazon ElastiCache for Redis now supports encryption for secure internode communications to help keep personally identifiable information (PII) safe. Both encryption in transit and at rest are supported. The new encryption in-transit feature enables you to encrypt all communications between clients and Redis servers as well as between Redis servers (primary and read replica nodes). The encryption at-rest feature allows you to encrypt your ElastiCache for Redis backups on disk and in Amazon S3. Additionally, you can use the Redis AUTH command for an added level of authentication.

If you are in the Financial Services, Healthcare, and Telecommunications sectors, this new encryption functionality can help you protect your sensitive data sets and meet compliance requirements. You can start using the new functionality by enabling it at the time of cluster creation via the ElastiCache console or through the API. You don’t have to manage the lifecycle of your certificates because ElastiCache for Redis automatically manages the issuance, renewal, and expiration of your certificates. For more information, see Enabling In-Transit Encryption and Enabling At-Rest Encryption.

There is no additional charge to use this feature, and it is available in the US West (Oregon), US West (N. California), US East (Ohio), US East (N. Virginia), Canada (Central), EU (Ireland), and South America (São Paulo) Regions. We will make this feature available in other AWS Regions as well.
